What animals eat a kowhai tree?

Kowhai trees (Sophora microphylla) are not typically eaten by animals. They are actually toxic to most animals, particularly horses and cattle.

Here's why:

* Toxic Compounds: Kowhai trees contain a compound called sophoridine, which is a poisonous alkaloid. This compound can cause serious health issues in animals that ingest it.

* Unpalatable Taste: The leaves and pods of kowhai trees have a bitter, unpleasant taste that discourages most animals from eating them.

However, there are a few exceptions:

* Birds: Some bird species, such as the kereru (New Zealand pigeon) and the tui, have been observed eating kowhai seeds. They seem to have a tolerance for the toxins, but they are not a major food source for these birds.

* Insects: Certain insects, such as caterpillars, may feed on kowhai leaves, but their impact is minimal.

It's important to note that the toxicity of kowhai trees can vary depending on factors like the age of the tree and the specific part ingested.

If you have a kowhai tree on your property, it's best to keep animals away from it to ensure their safety.
